Click the Create your app button; most inputs are optional, just provide your app with a name like Spotify Wrap. Next copy the below URL into the 'Redirect URI' input (click button): https://spotify-wrap.vercel.app/callback
*Note: none of your personal or Spotify information is being stored or collected. To assure safety concerns, afterwards you can delete the app you created on the Spotify Developers Website preventing any access to your Spotify info, by deleting the Client Id used to access it.*
